Which statement is accurate concerning heating systems?

Efficiency levels of oil furnaces are limited to mid-70%
Gas furnaces do not require a heat exchanger
Boiler systems can be either closed or open
Boiler hot water systems boil water

The correct answer is: Boiler systems can be either closed or open

Boiler systems can be either closed or open. This statement is accurate concerning heating systems. Boiler systems are a type of heating system that can operate in either a closed or open system. In a closed system, the water used for heating circulates in a closed loop and is not exposed to the atmosphere. In an open system, the water is heated and then released into the surrounding environment, and fresh water is brought in to replace it. The versatility of boiler systems to operate in both closed and open configurations makes them suitable for various heating needs.
